Potential disease agents in domestic goats and relevance to bighorn sheep (Ovis canadensis) management. [PDF]
Domestic goats are raised for meat, milk and hair production, in herds for rangeland weed control, and as pack animals. Domestic sheep, goats and wild bighorn sheep are all susceptible to a multifactorial pneumonia.

Local extinction and unintentional rewilding of bighorn sheep (Ovis canadensis) on a desert island. [PDF]
Bighorn sheep (Ovis canadensis) were not known to live on Tiburón Island, the largest island in the Gulf of California and Mexico, prior to the surprisingly successful introduction of 20 individuals as a conservation measure in 1975.

Regional variability in pregnancy and survival rates of Rocky Mountain bighorn sheep
In the Rocky Mountains, bighorn sheep restoration has been only marginally effective; this iconic wilderness species currently exists at a fraction of their historic abundance and often in fragmented and small populations.

Epizootic pneumonia of bighorn sheep following experimental exposure to Mycoplasma ovipneumoniae. [PDF]
Bronchopneumonia is a population limiting disease of bighorn sheep (Ovis canadensis). The cause of this disease has been a subject of debate. Leukotoxin expressing Mannheimia haemolytica and Bibersteinia trehalosi produce acute pneumonia after ...

REPRODUCTIVE STRATEGIES OF DESERT BIGHORN SHEEP [PDF]
We examined temporal breeding patterns of bighorn sheep (Ovis canadensis) in the Peninsular Ranges of California to determine the degree of seasonality and identify potential selection for seasonal breeding in this low-latitude desert environment.

Desert bighorn sheep in Mexico
The management of bighorn sheep in Mexico is not based on empirical data. We conducted phone interviews and a literature review to determine published information on desert bighorn sheep in Mexico. Most information on bighorn sheep was published prior to

Elaeophorosis in Bighorn Sheep in New Mexico [PDF]
Two bighorn sheep (Ovis canadensis) in New Mexico (USA) were found to be naturally infected with Elaeophora schneideri. An adult ram examined in 1997 in the Fra Cristobal Mountains had 26 nematodes in the carotid and iliac arteries, and microfilariae were present in the skin, nasal mucosa, brain, and lungs.

CONDUCTIVE HEARING LOSS IN BIGHORN SHEEP [PDF]
In January 1993 we simulated a conductive hearing loss in three Mexican bighorn sheep (Ovis canadensis mexicana) by placing bone wax or saline solution in their ear canals. Our objective was to test whether lesions of the external auditory canal caused by psoroptic mites (Psoroptes ovis) may lead to conductive hearing loss in bighorn sheep. We assessed

IntroductionThroughout their range, bighorn sheep (Ovis canadensis) populations have seen significant disease-associated declines. Unfortunately, understanding of the underlying epidemiological processes driving the disease dynamics in this species has ...
